To all whom t may cmwefm:

'Ee it known that l, lViLLiAM Enns'fns livllninivis, e citizen of the United States, e residen; of "Wilniette, in the' county of Cook end State of llinois, have invented the new und useful improvement' in teenforced Dish lheelsj of which the following' is it specification.

invention is to provide cheaply inside und he suilioiently light and yit stift eiound the hub Zone Without the necessity oi', employing what is known as e tapered disk foi? the web of the Wheel. and in place if using' s tapered disk l reinforce the'disk by e. seoondm'y disk around the 'hub zone. l

- The invention is set foth inthe claims.

Reference willvbe had to the accompanyd ing drawings in which Figure l is :i front elevation of e wheel. 'f

lfgnie 2 is :i sectional elevation.

vlfiguie 3 is en enlarged detail showing :ilteinntive construction.

ln the drawings 1 indicates the huh of an automobile wheel herein shown :is lieing a rent Wheel 'of a peculiar type. 2 indicates the brake dfum and 3 indicates the fini, here shown as the'typglmown ns quick detachable, used with a= straight side tire and provided with 'the detachable side ring The wel) oiI my Wheel l prefer to ineke ot it lisis oi ,metal of uniform thickness, forming wil-.it innjf he termed the front o1- outside ince of the Wheel and this disk is of relatively light material und is shaped with an annular seat 5 on the hul) bai-rel. which seat forms a part of a flange or margin of n stiziight faced portion of the disk G. through 'which there passes n series of stud bolts 7 securely fastened into e. flange 8 ot the huh lund provided with nuts 9 adapted to screw 7- und thereby fasten the disk on to the studs Lock washers 10 to the hub in o osliion.

Theshouldei's are i'oiined by dies or rollers and one at leestis formed after the i'ini and disk areplacedin piopei'vi'elutive positions; :ind as a further security, the i'ini und disk are united by spot welds lll,

To assist the mein oi' iiontdisk in sus- 6 taining strains neat' the hul) lf' provide "a secondary oi' reinforcing dish ofi the inside of the niain disk. which .ieiulioicing disk terminates in a region not quite midway lictween the huh fastening end the fini, :is indicated by 20. 'llliis secondary disk tits the convolutions of the front or nisin disk inthe scn'ie'm'unnei' Athough it. were :i unitary pzut thereof, and an inclined portion of this secondiii'y disk,

vof reinforcing' the main disk by the arrangement of the shapes described, l also conneet the two disks hy othensuitalile means, g., e seiies ot' spaced spot Yields in the inneiI and outei` zones, (i, 25,'of the, reinforcing disk. v

This also is assisted by the fastening nuts 9 which clamp the. two parts together in this iegion. The spot welds in this zone' 6 are indicated by 26 and may he placedat other sections of the contacts between the two disks, :is may he desired.'

|Thus by means oi making the ieinforcing disk fit the main disk in the shapes as shown, l ein able to Ineke Yei'y'cheztn wheel and at the sn'nie tiiner n light oneinelting iinnecessary the piepnie'dtapered disk which is en'expensiveitein to make compared with the flat sheets whi compose my two disks.

in place of securing the disk to the rim. as shown in Figure 2 and described I may, if l choose turn the outer edge ofthe main disk inwardly in the form of a flange 28 and secure it to the rim by the rivets 29 as shown'in Figure 3.

What l claim is:-

1. In a device of the class described, a relatively thin disk forming the front face of a Wheel and of uniform thickness and `provided with a series of inclined faces around the hub zone; in combination with a reinforcing disk on the inside of the Wheel and fitting the convolutions of'vr the main ln a ,device of the class described, a disk forming the ygeb of the Wheel and/'being relatively thin and of uniform section.; inconibination with a reinforcing disk for a distance aroundthe hub zone and the two 'disks unitedI together and having convolutions forming shoulders adapted to aid the main disk in transmitting its load to the reinforcing disk.

3.' ln a device of the class' described, the combination Witha main disk of'uniform thickness having a central inarginallyu flanged hub receiving opening surrounded by a normally vvertical plane zone', of a series of fastening screws passing through this zone, which merges peripherally into an inwardly inclined zone continuous peripherally with successive concave and convexannular zones and with a wider concave zone extending to the rim, and a central reinforcing disk fitting throughout its extent the various main disk'zones which it overlaps.

body portion for the outside of the Wheel; in combination with a4 reinforcing disk around theV hub Zone covering the convex portions ofthe main disk.

6. In a Wheel of the class described, a disk of uniform thickness form-ing the main web of the Whee and having a series of annular tion with a reinforcing disk dished outward 'from the hub and fitting closely theconvolutions of -the main disk and united to the main -dislLat dierent points.

. 8. In a wheel of the class described, a main .disk forming the main web ,of the Wheel,

concave as relates to the region approach ing vthe rim and convex as to the region around the hub Zone and reenforced with a secondary disk fitting on the inside ofthe main disk and fastening thereto.

, 9. In a Wheel of .the class described, a disk forming the main .web of the Wheel of relatively thin metal, a rim having an in- Ward projecting portion and the said disk secured` to the 'rim` on this inward prdjecting portion by means ofhaving the margin' of the disk curved to form'ashoulder on each side of the inward projecting'portion of the rim.

l0. In a Wheel of the class described, a

concave diskforming the major portion of the web of the Wheel and joined to the rim Abyhaving the margin of the disk forme into ribs adapted to embrace both sides of a Vnarrovvportion of the rim; in combination with a rim having a narrow inwardly extended portion to which the disk is secured. f 'r Signed at Chicago, in the county of Cook and State of Illinois, tlis 28th day of March, 1922.
